The effect of plant invasion on soil microbial carbon-use efficiency in semiarid grasslands of the Rocky Mountain West

Megan Nasto, Morgan McLeod, Lorinda Bullington, Ylva Lekberg & John Stark
1. Grassland ecosystems invaded by exotic plant species often exhibit substantially higher aboveground productivity and soil nitrogen (N) than the native communities they replace. These shifts are likely associated with altered microbial carbon (C) and N cycling, but we know surprisingly little about how these processes change with plant invasion. 2. Targeting four invasive plant species common in the Rocky Mountain West, we collected soils from invaded and adjacent uninvaded grassland field plots, as well...

Data for behavioral state-dependent habitat selection analysis of translocated female greater sage-grouse, North Dakota 2018-2020

Simona Picardi, Peter Coates, Jesse Kolar, Shawn O'Neil, Steven Mathews & David Dahlgren
This dataset is associated with the article, "Behavioral state-dependent habitat selection and implications for animal translocations" (Picardi et al., 2021, Journal of Applied Ecology). Post-release monitoring of translocated animals can be used to inform future translocation protocols. In particular, quantifying habitat selection of translocated individuals may help identify features that characterize suitable settlement habitat and inform the choice of future release sites; however, because translocated animals undergo post-release behavioral modification, the underlying behavioral state needs...

Cytotype and genotype predict mortality and recruitment in Colorado quaking aspen (Populus tremuloides)

Benjamin Blonder, Courtenay Ray, James Walton, Marco Castaneda, K. Dana Chadwick, Michael Clyne, Pierre Gaüzere, Lars Iversen, Madison Lusk, G. Richard Strimbeck, Savannah Troy & Karen Mock
Species responses to climate change depend on environment, genetics, and interactions among these factors. Intraspecific cytotype (ploidy level) variation is a common type of genetic variation in many species. However, the importance of intraspecific cytotype variation in determining demography across environments is poorly known. We studied the tree species quaking aspen (Populus tremuloides), which occurs in diploid and triploid cytotypes. This widespread species is experiencing contractions in its western range, which could potentially be linked...

Data from: Relative bee abundance varies by collection method and flowering richness: implications for understanding patterns in bee community data

Philip Hahn, Marirose Kuhlman, Skylar Burrows, Dan Mummey & Philip Ramsey
Pollination by wild bees is a vital ecosystem process in natural and managed systems. Recent declines in wild bee populations have led to increases in conservation actions and monitoring of bee communities. Pan traps are a commonly used sampling method for monitoring bee populations due to their efficiency and low cost. However, potential biases inherent in different sampling techniques may result in misleading characterizations of bee communities across space and time. In this paper, we...

Data from: Integrating tracking and resight data enables unbiased inferences about migratory connectivity and winter range survival from archival tags

Clark Rushing, Aimee Van Tatenhove, Andrew Sharp, Viviana Ruiz-Gutierrez, Mary Freeman, Paul Sykes, Aaron Given & Scott Sillett
Archival geolocators have transformed the study of small, migratory organisms but analysis of data from these devices requires bias correction because tags are only recovered from individuals that survive and are re-captured at their tagging location. Data and code provided in this repository can be used to replicate the simulation and Painted Bunting case study results presented by Rushing et al. (2021) showing that integrating geolocator recovery data and mark–resight data enables unbiased estimates of...

Improving intra- and inter-annual GPP predictions by using individual-tree inventories and leaf growth dynamics

Jing Fang, James Lutz, Herman Shugart, Xiaodong Yan, Wenqiang Xie & Feng Liu
Carbon sequestration is a key ecosystem service provided by forests. Inventory data based on individual trees are considered to be the most accurate method for estimating forest productivity. However, estimations of forest photosynthesis itself from inventory data remains understudied, particularly when considering the growth and development of individual trees under the background of global change. Here, we used the leaf growth process with phenology and non-structural carbohydrates (NSC) storage to revise an individual-tree based carbon...

Genomic time-series data show that gene flow maintains high genetic diversity despite substantial genetic drift in a butterfly species

Zachariah Gompert, Amy Springer, Megan Brady, Samridhi Chaturvedi & Lauren Lucas
Effective population size affects the efficacy of selection, rate of evolution by drift, and neutral diversity levels. When species are subdivided into multiple populations connected by gene flow, evolutionary processes can depend on global or local effective population sizes. Theory predicts that high levels of diversity might be maintained by gene flow, even very low levels of gene flow, consistent with species long-term effective population size, but tests of this idea are mostly lacking. Here,...

Spatial personalities: a meta-analysis of consistent individual differences in spatial behavior

Erica Stuber, Ben Carlson & Brett Jesmer
Individual variation in behavior, particularly consistent among-individual differences (i.e., personality), has important ecological and evolutionary implications for population and community dynamics, trait divergence, and patterns of speciation. Nevertheless, individual variation in spatial behaviors, such as home range behavior, movement characteristics, or habitat use has yet to be incorporated into the concepts or methodologies of ecology and evolutionary biology. To evaluate evidence for the existence of consistent among-individual differences in spatial behavior – which we refer...

A population-genomic approach for estimating selection on polygenic traits in heterogeneous environments

Zachariah Gompert
Strong selection can cause rapid evolutionary change, but temporal fluctuations in the form, direction and intensity of selection can limit net evolutionary change over longer time periods. Fluctuating selection could affect molecular diversity levels and the evolution of plasticity and ecological specialization. Nonetheless, this phenomenon remains understudied, in part because of analytical limitations and the general difficulty of detecting selection that does not occur in a consistent manner. Herein, I fill this analytical gap by...

A machine learning approach to integrating genetic and ecological data in tsetse flies (Glossina pallidipes) for spatially explicit vector control planning

Anusha Bishop, Giuseppe Amatulli, Chaz Hyseni, Evlyn Pless, Rosemary Bateta, Winnie Okeyo, Paul Mireji, Sylvance Okoth, Imna Malele, Grace Murilla, Serap Aksoy & Norah Saarman
Introduction - Control of vector populations is an effective strategy for addressing vector-borne disease transmission. Effective vector control requires knowledge of habitat use and connectivity. Our goal was to improve this knowledge for the tsetse species Glossina pallidipes, a vector of animal African trypanosomiasis, which is a wasting disease in livestock and represents a serious socioeconomic burden across sub-Saharan Africa. Methods and Results - We used random forest regression to: (i) Build and integrate models...

Lignin concentrations in phloem and outer bark are not associated with resistance to mountain pine beetle in high elevation pines

David Soderberg
A key component to understanding plant-insect interactions is the nature of host defenses. Research on defense traits among Pinus species has focused on specialized metabolites and axial resin ducts, but the role of lignin in defense within diverse systems is unclear. We investigated lignin levels in the outer bark and phloem of P. longaeva, P. balfouriana, and P. flexilis; high elevation species in the western United States known to differ in susceptibility to mountain pine...

Energy pathways modulate the resilience of stream invertebrate communities to drought

Daniel Nelson, Michelle Busch, Darin Kopp & Daniel Allen
1. While climate change is altering ecosystems on a global scale, not all ecosystems are responding in the same way. The resilience of ecological communities may depend on whether food webs are producer- or detritus-based (i.e. “green” or “brown” food webs, respectively), or both (i.e. “multi-channel” food web). 2. Food web theory suggests that the presence of multiple energy pathways can enhance community stability and resilience and may modulate the responses of ecological communities to...

Recolonizing carnivores: Is cougar predation behaviorally mediated by bears? Cougar Killsite Data

Julie Young, Jon Beckmann & Kristin Engebretsen
Conservation and management efforts have resulted in population increases and range expansions for some apex predators, potentially changing trophic cascades and predatory behavior. Changes in sympatric carnivore and dominant scavenger populations provide opportunities to assess how carnivores affect one another. Cougars (Puma concolor) were the apex predator in the Great Basin of Nevada, USA, for over 80 years. Black bears (Ursus americanus) have recently recolonized the Great Basin and are known to heavily scavenge on...

Capabilities and limitations of using DNA metabarcoding to study plant-pollinator interactions

Katherine Arstingstall, Sandra DeBano, Xiaoping Li, David Wooster, Mary Rowland, Skyler Burrows & Kenneth Frost
Many pollinator populations are experiencing declines, emphasizing the need for a better understanding of the complex relationship between bees and flowering plants. Using DNA metabarcoding to describe plant-pollinator interactions eliminates many challenges associated with traditional methods and has the potential to reveal a more comprehensive understanding of foraging behavior and pollinator life history. Here we use DNA metabarcoding of ITS2 and rbcL gene regions to identify plant species present in pollen loads of 404 bees...

Do fine-scale experiments underestimate predator consumption rates?

Lindsey Bruckerhoff, Casey Pennock & Keith Gido
Understanding ecological processes across spatial scales helps link observations and predictions from experiments to ecological patterns occurring at coarser scales relevant to management and conservation. Using fish, we experimentally manipulated the size of arenas to test the spatial scaling of predator-prey interactions. We measured variation in predator consumption and prey behavior (prey aggregation, spatial overlap with predators, and movement) across arena sizes. Variation in prey behavior across arena sizes was hypothesized to drive consumption patterns...

Data from: Fractal triads efficiently sample ecological diversity and processes across spatial scales

Elizabeth Simpson & William Pearse
The relative influence of ecological assembly processes, such as environmental filtering, competition, and dispersal, vary across spatial scales. Changes in phylogenetic and taxonomic diversity across environments provide insight into these processes, however, it is challenging to assess the effect of spatial scale on these metrics. Here, we outline a nested sampling design that fractally spaces sampling locations to concentrate statistical power across spatial scales in a study area. We test this design in northeast Utah,...

Digital Appendix of Masters Thesis \"Constraining deformation mechanisms of damage zones: A case study of the shallow San Andreas Fault at Elizabeth Lake, Southern California\"

James Evans & Caroline Studnicky
We performed macroscopic, optical petrographic, scanning electron microscopy, and geochemical analyses on rock core acquired across the San Andreas Fault at Elizabeth Lake, California, in order to understand the distribution and accommodation of fault-related slip and energy within the shallow damage zone of this continental scale strike-slip fault. We characterized the deformation structures, alteration textures, and elemental variabilities to constrain the properties of the uppermost ~2 km fault-related damage zone at this site. We identified...
